I had similar problems - note I said HAD. I've had foot cramping problems for several years, and they just kept getting worse. Two days prior to my IDET I was getting constant foot cramps (mainly right foot). All I had to do was point my foot and they'd come on with a vingence. Then, I had the IDET and they're almost completely gone away. Weird coincidence, eh? The nurse in the pain clinic told me leg and foot cramps can be caused by back "injuries"/degeneration due to the dermatone levels - nerve lines from the back that innervate different areas of the body.
